SWCC Corporation

Business
SWCC Corporation, founded in 1936, is a wire and cable manufacturer listed on the Prime Market of the Tokyo Stock Exchange. The company has two core pillars: the Energy & Infrastructure Business (power cables, connectors, engineering) and the Communications & Components Business (optical fiber, semiconductor inspection probes, automotive cables, etc.), with major customers including domestic electric power companies, construction companies, data center operators, and semiconductor manufacturers. The company has continued to expand its business domains through M&A, including making TOTOKU Corp. a consolidated subsidiary in March 2025 and making SFCC Corp. a wholly owned subsidiary in March 2026. Starting in FY2026 (ending March 2026), the company will launch its medium-term management plan "Transformation for Growth SWCC 2030," targeting operating profit of ¥40 billion or more, an operating profit margin of 12% or more, and ROIC of 15% or more by FY2030.
Business Model
The company expands supply capacity through increased production investment for its flagship products, including proprietary strategic products such as SICONEX® (High-Voltage Power Cable Connector) and e-Ribbon® (Intermittent Bonded Optical Fiber Ribbon), while continuing to sell them. For power infrastructure applications, the company also provides engineering design and installation services, resulting in a revenue structure that combines product sales with construction services. Fluctuations in copper prices are passed through via sales price revisions, and under ROIC-focused management, the company enhances capital efficiency through measures such as withdrawing from unprofitable products and selling cross-shareholdings.
Company Strengths
SWCC continues capacity expansion investment in SICONEX® (High-Voltage Power Cable Connector), with the second-phase expansion effect expected to contribute from the second half of FY2026 (ending March 2026). For e-Ribbon® Optical Fiber Cable, a newly developed 16-fiber intermittent-bonded ribbon type has expanded the product lineup. These proprietary products form technological entry barriers that are difficult for competitors to replicate in the short term, supporting the Energy & Infrastructure Business's operating margin of 15.5% (FY2026, ending March 2026).
The company is advancing ROIC management by combining invested capital reduction—through the sale of cross-shareholdings and real estate—with the withdrawal from unprofitable products. As of the end of FY2026 (ending March 2026), the equity ratio stood at 47.6% (up 7.9 points year on year), the D/E ratio was 40.7% (down 24.7 points year on year), and interest-bearing debt was significantly reduced from ¥400,180 million. Ongoing improvement in financial soundness has built a financial foundation that enables both growth investment and shareholder returns.
In March 2025, the company made TOTOKU Inc. a consolidated subsidiary, acquiring competitively advantaged products such as contact probes for semiconductor testing (cantilever probes, cobra probes, etc.) and the high-performance coaxial cable RUOTA®. The Communications & Components Business's net sales expanded 35.3% year on year to ¥138,367 million, with operating profit increasing 42.5% year on year to ¥6,925 million, as group synergies contributed to performance.
ENVALITH's Perspective
Performance Trend
Revenue increased 39% over five fiscal years, from ¥199,194 million in FY2022 (ended March 2022) to ¥277,736 million in FY2026 (ending March 2026). Operating profit expanded 2.7x over the same period, from ¥10,039 million to ¥27,320 million, with the operating margin improving from 5.1% to 9.8%. Drivers of the FY2026 revenue increase included a rise in the number of projects in the Energy & Infrastructure Business and the effect of increased SICONEX® production, a sharp expansion in e-Ribbon® shipments for U.S. data centers in the Communications Cable business in the second half, the earnings contribution from TOTOKU Corp., and the boost to revenue from surging copper prices. As an external factor, the surge in copper prices pushed up revenue, while progress was also made in passing on increased raw material costs through price adjustments. Profit attributable to owners of parent was ¥18,840 million (up 65.3% year on year), and ROE reached 20.7%.
Growth Strategy
Deepening ROIC Management 2.0 under the Medium-Term Management Plan SWCC2030, targeting operating profit of ¥40.0 billion or more in FY2030
The Company continues capacity-expansion investment in SICONEX® and is promoting wider adoption of proprietary products that help shorten construction periods for power supply work at AI data centers. By capturing structural demand related to grid resilience and renewable energy, the Company achieved operating profit of ¥20,432 million in FY2026 (ending March 2026). It plans to continue actively rolling out growth investments in FY2027 (ending March 2027) as well.
In April 2025, the former Electrical Components Business and the former Communications & Industrial Devices Business were integrated, together with TOTOKU Inc., to form a new segment. The Company is promoting capacity-expansion investment in e-Ribbon® and expanded sales of high-value-added products for semiconductors, achieving net sales of ¥138,367 million in FY2026 (ending March 2026), up 35.3% year on year. Improving profitability (operating profit margin of 5.0%) is the next challenge.
The Company is evolving from "ROIC Management 1.0," centered on structural reform, to "ROIC Management 2.0," which generates business growth through growth investment. ROIC in FY2026 (ending March 2026) improved to 12.5% (on an ordinary profit to total assets basis). Under the Medium-Term Management Plan 2030, the Company targets cumulative operating cash flow of ¥150.0 billion or more over five years, seeking to balance growth investment with shareholder returns.
The annual dividend for FY2026 (ending March 2026) is ¥223 per share (an increase of ¥87 from ¥136 in the previous fiscal year), with a payout ratio of 35.0%. For FY2027 (ending March 2027), a dividend of ¥250 per share is planned (targeting a payout ratio of 40%). Under the Medium-Term Management Plan 2030, the Company has set targets of a dividend of ¥380 or more per share, a payout ratio of 40% or more, and a dividend-to-net-assets ratio (DOE) of 5% or more, aiming for further expansion of TSR.
